摘要：
A method for producing heat exchange between particles of raw materials and hot combustion gases in an inclined rotary kiln is disclosed. The kiln includes trough-shaped conveyor flights constructed to discharge the particles over the length of the kiln in the form of clouds of substantially parallel vertical curtains extending across the kiln at an acute angle to the axis of the kiln. The kiln can be used in a plant including means for collecting and returning the material carried out of the kiln.
